onButtonClick wird nie im Quellcode verwendet?

Question

Ich schreibe eine einfache App, die gut funktioniert, aber das Problem, das ich habe, ist, dass ich eine Passwort-Bedingung verwende, um einen Knopfklick auszulösen, wenn richtig eingegeben.

Das Problem ist, dass mein Quellcode sagt "OnButtonClick" wird nie verwendet und wenn ich manuell auf diese Schaltfläche in der App drücken, wird es plötzlich zwangsweise geschlossen und stürzt ab. Jeder weiß, was ich falsch mache. Ich erweitere Activity, am Anfang des Quellcodes. Sollte ich erweitern AppCompatActivity?

public class Gvoice extends Activity implements OnClickListener{ 

ListView lv1; 
static final int check = 1111; 
Button b1; 
Button b_home; 
EditText a1; 


@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.gvoice); 
    lv1 = (ListView)findViewById(R.id.LVGVoiceReturn); 
    b1 = (Button)findViewById(R.id.GVoice); 
    a1 = (EditText) findViewById(R.id.editTextHome); 
    b1.setOnClickListener(this); 

    //This now handles an automatic press of the bVoice button 1 second after the activity is opened 
    new Handler().postDelayed(new Runnable() { 
     @Override 
     public void run() { 
      b1.callOnClick(); 
     } 
    }, 1000); 

} 

public void onButtonClick(View v) { 
    if (v.getId() == R.id.BHome) { 
     String str = a1.getText().toString(); 


     //Go to the relevant page if any part of the phrase or word entered in the 'EditText' field contains 'xxx' which is not case sensitive 
     if (str.toLowerCase().contains("home")) { 
      Intent userintent = new Intent(Gvoice.this, PocketSphinxActivity.class); 
      startActivity(userintent); 
     } else { 
      Toast.makeText(getApplicationContext(), "Incorrect Information", Toast.LENGTH_SHORT).show(); 
     } 
    } 
} 

public void onClick(View v){ 
Intent i1 = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH); 
    i1.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM); 
    i1.putExtra(RecognizerIntent.EXTRA_PROMPT, "Please Repeat Again"); 
    startActivityForResult(i1, check); 
} 

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 

    if (requestCode == check && resultCode == RESULT_OK){ 
     ArrayList<String> results = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS); 
     lv1.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, results)); 
     a1.setText((String) lv1.getItemAtPosition(0)); //Get the first phrase in the first row of list view 

     Handler handler = new Handler(); 
     handler.postDelayed(new Runnable() { 
      @Override 
      public void run() { 
       b_home.performClick(); 
      } 
     }, 500); //Automatically click the 'Blogin' button after 500ms 
    } 

    super.onActivityResult(requestCode, resultCode, data); 
} 

} 

Update: Unten ist die XML-Datei. Bitte beachten Sie, dass onButtonClick hat zu der XML-Datei hinzugefügt worden, aber es immer noch Kraft schließt die App, wenn die Taste, um die Bedingungsanweisung geklickt wird unter Verwendung von:

Answer 1

Sie kann 4 Methode Griff-Taste klicken:

Methode 1:

public class Mtest extends Activity { 

    Button b1; 
    public void onCreate(Bundle savedInstanceState) { 
    ... 
    Button b1 = (Button) findViewById(R.id.b1); 
    b1.setOnClickListener(myhandler1); 
    ... 
    } 
    View.OnClickListener myhandler1 = new View.OnClickListener() { 
    public void onClick(View v) { 
     // it was the 1st button 
    } 
    }; 

} 

Methode 2:

class MTest extends Activity implements OnClickListener { 
    public void onCreate(Bundle savedInstanceState) { 
    ... 
    Button b1 = (Button) findViewById(R.id.b1); 

    b1.setOnClickListener(this); 
     ... 
    } 

    @Override 
    public void onClick(View v) { 

    } 
} 

Methode 3 in xml und Android: onClick = "handle":

<Button 
    android:id="@+id/button2" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:onClick="HandleClick" /> 



public class MTest extends Activity { 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 
    } 
    public void HandleClick(View view) { 

    } 
} 

Methode 4:

public class MTest extends Activity { 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 
     Button b1 = (Button) findViewById(R.id.b1); 
     b1.setOnClickListener(new OnClickListener() { 
      public void onClick(View view) { 
       // do stuff 
      } 
     }); 

    } 
} 

Answer 2

Das Problem war mit anfangs nicht das Hinzufügen onButtonClick in der XML-Datei zu tun, und auch Die Schaltflächenbezeichnungen in der Java-Datei werden nicht korrekt zugewiesen.

lv1 = (ListView)findViewById(R.id.LVGVoiceReturn); 
    b1 = (Button)findViewById(R.id.GVoice); 
    a1 = (EditText) findViewById(R.id.editTextHome); 
    c1 = (Button)findViewById(R.id.BHome); 

    b1.setOnClickListener(this); 

Das folgende korrigiert die Probleme und alles funktioniert jetzt gut. Hoffe, das kann anderen in der Zukunft helfen
