Would someone kindly suggest why the code in the OnKey() method is not executing. Please note that I am attempting to trigger this my hitting the "Search" button on the android key board.
Here is the main code:
package com.onkeyexample1; import android.app.Activity; import android.os.Bundle; import android.text.Editable; import android.text.TextWatcher; import android.util.Log; import android.view.KeyEvent; import android.view.View; import android.view.View.OnKeyListener; import android.widget.EditText; public class OnKeyExample1Activity extends Activity { EditText editText; OnKeyListener onKeyListener; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); editText = (EditText) findViewById(R.id.editText1); editText.setOnKeyListener(onKeyListener); editText.addTextChangedListener(inputTextWatcher); onKeyListener = new OnKeyListener() { @Override public boolean onKey(View v, int keyCode, KeyEvent event) { System.out.println("Clicked"); return true; } }; } I tried adding the block of code below as a suggested fix but it didn't help:
private TextWatcher inputTextWatcher = new TextWatcher() { public void afterTextChanged(Editable s) { } public void beforeTextChanged(CharSequence s, int start, int count, int after) { } public void onTextChanged(CharSequence s, int start, int before, int count) { // Log.d(TAG, s.charAt(count-1) + " character to send");; } }; } Here is my layout xml:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" /> <EditText android:imeOptions="actionSearch" android:layout_width="fill_parent" android:id="@+id/editText1" android:layout_height="wrap_content"> <requestFocus></requestFocus> </EditText> </LinearLayout> Any suggestions are greatly appreciated!
Here is the first implementation of Ted's suggestion:
public class OnKeyExample1Activity extends Activity { EditText editText; OnKeyListener onKeyListener; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); editText = (EditText) findViewById(R.id.editText1); editText.setOnKeyListener(onKeyListener = new OnKeyListener() { @Override public boolean onKey(View v, int keyCode, KeyEvent event) { System.out.println("Clicked"); return true; } }); } } Here's the fix to the double trigger problem mentioned in my comment:
editText.setOnKeyListener(onKeyListener = new OnKeyListener() { @Override public boolean onKey(View v, int keyCode, KeyEvent event) { if (event.getAction() != KeyEvent.ACTION_DOWN) { System.out.println("Argh"); return false; } return true; } }); }
