無鍵盤ID 0使用默認的鍵盤對應：/system/usr/keychars/qwerty.kcm.bin

Question

我的應用程序停止當我點擊btn_shapes在此代碼。該btn_alphabet和btn_know工作正常，但在btn_shapes的申請停止。無鍵盤ID 0使用默認的鍵盤對應：/system/usr/keychars/qwerty.kcm.bin

public class Eng extends Activity implements OnClickListener { 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    // TODO Auto-generated method stub 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.eng); 

    Button alphabet = (Button) findViewById(R.id.btn_alphabet); 
    alphabet.setOnClickListener((OnClickListener)this); 

    Button bshapes = (Button) findViewById(R.id.btn_shapes); 
    bshapes.setOnClickListener((OnClickListener)this); 

    Button know = (Button) findViewById(R.id.btn_know); 
    know.setOnClickListener((OnClickListener)this); 

} 

public void onClick(View v) { 
    // TODO Auto-generated method stub 
    switch(v.getId()){ 

    case R.id.btn_alphabet: 
     Intent s_alphabet = new Intent(this, Alphabet.class); 
     startActivity(s_alphabet); 
     break; 

    case R.id.btn_shapes: 
     Intent s_shapes = new Intent(this, Bshapes.class); 
     startActivity(s_shapes); 
     break; 

    case R.id.btn_know: 
     Intent s_know = new Intent(this, Know.class); 
     startActivity(s_know); 
     break; 

    } 

} 

}
