android - 如何避免在android中同时单击多个按钮？

Question

我在 View 中使用了两个按钮。同时单击两个按钮时，它将一次进入不同的 Activity 。如何避免这种情况？

我试过这样，但它不起作用请保存....

public class MenuPricipalScreen extends Activity {


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.menu_principal_layout);


    findViewById(R.id.imageView2).setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub

            disable(findViewById(R.id.imageView3));

            Intent intent = new Intent(MenuPricipalScreen.this,
                    SelectYourLanguageVideo.class);
            startActivity(intent);
        }
    });
    findViewById(R.id.imageView3).setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub

            disable(findViewById(R.id.imageView2));

            Intent intent = new Intent(MenuPricipalScreen.this,
                    CategoryScreen.class);
            intent.putExtra("request", "false");
            startActivity(intent);
        }
    });

}

 @Override
protected void onResume() {
    // TODO Auto-generated method stub
    super.onResume();
    ((ImageView) findViewById(R.id.imageView3)).setEnabled(true);
    ((ImageView) findViewById(R.id.imageView2)).setEnabled(true);
    ((ImageView) findViewById(R.id.imageView3)).setClickable(true);
    ((ImageView) findViewById(R.id.imageView2)).setClickable(true);
    ((ImageView) findViewById(R.id.imageView3)).setFocusable(true);
    ((ImageView) findViewById(R.id.imageView2)).setFocusable(true);
}

 private void disable(View v) {
    Log.d("TAG", "TAG" + v.getId());
    v.setEnabled(false);
    v.setClickable(false);
    v.setFocusable(false);
}
}

谢谢，

避免多次点击的标准方法是保存最后一次点击的时间并避免在 1 秒(或任何时间跨度)内点击其他按钮。示例:

// Make your activity class to implement View.OnClickListener
public class MenuPricipalScreen extends Activity implements View.OnClickListener{

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // setup listeners.
        findViewById(R.id.imageView2).setOnClickListener(MenuPricipalScreen.this);
        findViewById(R.id.imageView3).setOnClickListener(MenuPricipalScreen.this);
        ...
     }

    .
    .
    .

    // variable to track event time
    private long mLastClickTime = 0;

    // View.OnClickListener.onClick method defination

    @Override
    public void onClick(View v) {
        // Preventing multiple clicks, using threshold of 1 second
        if (SystemClock.elapsedRealtime() - mLastClickTime < 1000) {
            return;
        }
        mLastClickTime = SystemClock.elapsedRealtime();

        // Handle button clicks
        if (v == R.id.imageView2) {
            // Do your stuff.
        } else if (v == R.id.imageView3) {
            // Do your stuff.
        }
        ...
    }

    .
    .
    .

 }
