KeyEvent.KEYCODE_DPAD_DOWN就能监听到,换了KeyEvent.KEYCODE_DPAD_CENTER就没用。
代码附在下面。
log当中只能输出down。。求指导。。
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.KeyEvent;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.EditText;
public class MainActivity extends ActionBarActivity {
EditText mEditText;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mEditText=new EditText(this);
mEditText.setText("jj");
setContentView(mEditText);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
public boolean onKeyDown(int keyCode,KeyEvent msg)
{
if(keyCode==KeyEvent.KEYCODE_DPAD_CENTER)
{
Log.d("ke", "center");
}
if(keyCode==KeyEvent.KEYCODE_ENTER)
{
Log.d("ke", "center");
}
if(keyCode==KeyEvent.KEYCODE_DPAD_DOWN)
{
Log.d("ke", "down");
}
return true;
}
}
