No speakable text present android studio ошибка

My EditText does not work like the videos and articles I have found. The EditText does not show what the user inputted at the time of input or when I tell the output to show there, the hint I assigned it also does not show up. Right now I have the output going to a TextView but can greatly Reduce lines of code if I can get the EditText working properly. I am new to this and have troubles understanding. Thank you for the help.

Here is the xml file:

//DOES NOT SHOW INPUT AT TIME OF INPUT, OR WHEN TOLD TOLD BY OUTPUT. HINT DOES NOT SHOW EITHER-------
<EditText
android:id="@+id/MetalCounter"
android:layout_width="40dp"
android:layout_height="20dp"
android:layout_margin="4dp"
android:ems="10"
android:textAlignment="center"
android:textColor="#000000"
android:textSize="15sp"
android:hint="0"
android:textColorHint="#000000"
android:inputType="number"
app:layout_constraintRight_toLeftOf="@id/guideline"
app:layout_constraintTop_toBottomOf="@id/ResourceSubmitButton" />
 //is put in top left corner for testing purposes---------------------------------
<TextView
android:id="@+id/MetalResult"
android:layout_width="40dp"
android:layout_height="20dp"
android:layout_margin="4dp"
android:text=""
android:textAlignment="center"
android:textColor="#000000"
android:textSize="15sp"
 />

and here is the java file:

package com.example.game;
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
// These are the global variables
EditText MetalCounter;
TextView MetalResult;
Button ResourceSubmitButton;
int Metal;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    //to get from user input and into variable form
    MetalCounter = (EditText) findViewById(R.id.MetalCounter);
    MetalResult = (TextView) findViewById(R.id.MetalResult);
    ResourceSubmitButton = (Button) findViewById(R.id.ResourceSubmitButton);
    //Submit button
    ResourceSubmitButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            //to receive and show the inputted values into the MetalResult TextView
            MetalResult.setText(MetalCounter.getText().toString());
   
            //This is a test to see if the result would show up but does not
            Metal = Integer.parseInt(MetalCounter.getText().toString());
            MetalCounter.setText(MetalCounter.getText().toString());
        }
    });
}
}

Well, I think the problem lies here in this part

android:layout_width="40dp"
android:layout_height="20dp"
android:layout_margin="4dp"
android:ems="10"
android:textSize="15sp"

These attributes are not well-defined because you have set the

layout_margin

to 4dp which causes the view to shrink. so instead of having a width of 40dp, now you have a width of 32dps, similarly you have a height of only 12dps which is very small and doesn’t match with the selected

textSize


So, my suggestion is changing the width and height attributes to wrap_content as follows

android:layout_width="wrap_content"
android:layout_height="wrap_content"

and you can keep everything else as it’s.

Remarks

• Consider changing your variables to follow the
  
camelCase

  convention

// Before
EditText MetalCounter;
TextView MetalResult;
//After
EditText metalCounter;
TextView metalResult;

• Change the hint color’s opacity in order to differentiate it from the text itself
• If you still have a problem so it may be due to the constraints in the bottom. If so, please post the full layout file.

Much simpler than sniffing keys: try setting

android:singleLine="true"

and

android:imeOptions="actionNext"

(at least for single-line entry textviews). Read more in the Android documentation for TextView.

Update:


singleLine

is deprecated now, but you can leave it out. It’s the default behavior for editable text as long as you don’t explicitly set

android:inputType="textMultiLine"

, and

inputType

overrides the suggested

singleLine

replacement of

maxLines="1"

for editable text anyways.

For an alternative or a newer approach for the answer given from Yoni…

Since

singleLine

is considereded deprecated, we can set manually to

android:maxLines="1"

with

android:inputType="text"

.

Small explanation:

• We use
  
android:inputType="text"

  to specifically treat the input as plain text.
• And we use
  
android:maxLines="1"

  to set the max lines of the text to 1 (as it suggests).

Using

maxLines="1"

alone, will not cause any effect, but

inputType="text"

alone may work also, as Adam mentions (though I haven’t checked this).

Adding

    android:inputType="text"

in XML is just enough. When You are not defining input type, then it goes to next line.

You could try adding a single event listener to all your editText objects:

OnKeyListener myKeyListener = new OnKeyListener() {
        @Override
        public boolean onKey(View arg0, int arg1, KeyEvent arg2) {
            // TODO: do what you got to do
            return false;
        }
    };
editText1.setOnKeyListener(myKeyListener);
editText2.setOnKeyListener(myKeyListener);
editText3.setOnKeyListener(myKeyListener);

I use react native for Android, and I want to edit bunch of TextInput with the «next» option like here (ios version):
https://github.com/facebook/react-native/pull/2149#issuecomment-129262565

I tried:

<TextInput
    style = {styles.titleInput}
    returnKeyType = {"next"}
    autoFocus = {true}
    placeholder = "Title"
    onSubmitEditing={(event) => { 
    this.refs.SecondInput.focus(); 
  }}
/>
<TextInput
ref='SecondInput'
style = {styles.descriptionInput}
multiline = {true}
maxLength = {200}
placeholder = "Description" />

But the keyboard is close and open and that’s annoying.

from https://stackoverflow.com/a/4999372/1456487 i understand that in native android apps i would use:

android:imeOptions="actionNext"

Is there any way to do this?

This ability introduced in react-native .22 .

This is with Text Input Layout

in xml Layout file

 <android.support.design.widget.TextInputLayout
                android:id="@+id/input_layout_password"
                android:layout_width="match_parent"
                android:layout_height="wrap_content">
                <EditText
                    android:id="@+id/textView_password"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:hint="@string/password"
                    android:inputType="textPassword" />
</android.support.design.widget.TextInputLayout>

Your activity should be something like this.

passwordTIL = (TextInputLayout) findViewById(R.id.input_layout_password);
passwordET = (EditText) findViewById(R.id.textVIew_password);
passwordET.addTextChangedListener(new SigninTextWatcher(passwordET)
//you can use this for username too or to check if the email format is correct or not.
private class SigninTextWatcher implements TextWatcher {
        private View view;
        private SigninTextWatcher(View view) {
            this.view = view;
        }
        public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
        }
        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
        }
        public void afterTextChanged(Editable editable) {
            switch (view.getId()) {
                case R.id.textView_password:
                    validatePassword();
                    break;
            }
        }
    }
    private boolean validatePassword() {
        if (passwordET.getText().toString().trim().isEmpty()) {
            passwordTIL.setError("Empty error message");
            requestFocus(passwordET);
            return false;
        } else if(passwordET.getText().toString().length() < 6){
                passwordTIL.setError("Short password error message");
                requestFocus(passwordET);
                return false;
        }else {
                passwordTIL.setErrorEnabled(false);
            }
            return true;
        }

You can make use of validatePassword() function to enable/ disable login button too

You can use textChangedListener attached to your edit text.
See simple example:

Field1.addTextChangedListener(new TextWatcher() {
   @Override
   public void afterTextChanged(Editable s) {
    if(s.length() < 6)
       // show message too short
    }}
   @Override    
   public void beforeTextChanged(CharSequence s, int start,
   int count, int after) {
   }
   @Override    
  public void onTextChanged(CharSequence s, int start,
   int before, int count) {
  });

Use

et_password.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
        }
        @Override
        public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
            if(charSequence.length()<6){
                et_password.setError("The password must contain 6 characters");
            }
        }
        @Override
        public void afterTextChanged(Editable editable) {
        }
    });

Add addtextchangedlistener() to your editText.

    EditText password = (EditText) findViewById(R.id.password_et);
    password.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence charSequence, int i, int i2, int i3) {
        }
        @Override
        public void onTextChanged(CharSequence charSequence, int i, int i2, int i3) {
          if((charSequence.toString()).length < 6){
           Toast.makeText(this, "Password length less than 6", Toast.LENGTH_SHORT).show();
          }
        }
        @Override
        public void afterTextChanged(Editable editable) {
        }
});
