安卓OnClick的四種方法

1.匿名内部類

Button bt_dial = (Button) findViewById(R.id.bt_dial);

bt_dial.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View view) {

點選操作

}

});

2.自定義單擊事件監聽類

Button bt_dial = (Button) findViewById(R.id.bt_dial);

bt_dial.setOnClickListener(new MyListener());

private class MyListener implements View.OnClickListener {

@Override

public void onClick(View view) {

點選操作

}

3.Activity繼承View.OnClickListener

public class MainActivity extends Activity implements View.OnClickListener {
    EditText et_number;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        et_number = (EditText)    MainActivity.this.findViewById(R.id.et_number);        
    Button bt_dial = (Button) findViewById(R.id.bt_dial);
        bt_dial.setOnClickListener(this); 
    }
 
    public void onClick(View view) { 
        switch (view.getId()){
            case R.id.bt_dial:
                點選操作
                break;
            default:
                break;
        }
    }
}
           

4.在XML檔案中顯示指定按鈕的onClick屬性

public void dialPhoneMethod(View view){

       點選操作

    }
