下面是一个OnClickListener代理，它可以根据qezt的答案阻止连续的单击。

import android.os.SystemClock;
import android.view.View;

public class MultiClickGuard implements View.OnClickListener {    

    private long mLastClickTime;

    private final int mThresholdMillis;
    private final View.OnClickListener mListener;

    public MultiClickGuard(View.OnClickListener listener, int thresholdMillis) {
        if (listener == null) {
            throw new NullPointerException("Null OnClickListener");
        }
        if (thresholdMillis < 0) {
            throw new IllegalArgumentException("Negative click threshold: " + thresholdMillis);
        }

        mListener = listener;
        mThresholdMillis = thresholdMillis;
    }

    @Override
    public void onClick(View v) {
        // Using a time threshold to prevent successive clicks.
        if (SystemClock.elapsedRealtime() - mLastClickTime < mThresholdMillis) {
            return;
        }
        mLastClickTime = SystemClock.elapsedRealtime();

        // Forward the click event to the *real* listener.
        mListener.onClick(v);
    }
}

用法示例

button.setOnClickListener(new MultiClickGuard(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // do something
    }
}, 1000));

button.setOnClickListener(new MultiClickGuard(v -> {...}, 1000));
button.setOnClickListener(new MultiClickGuard(v -> doSomething(), 1000));

在试图阻止启动一个活动的多个实例的情况下，考虑指定启动模式:理解任务和返回堆栈，这是可靠的方式。

如果您试图阻止打开一个对话框片段的多个实例，您可以检查片段管理器是否已经包含了对话框，例如getSupportFragmentManager(). findfragmentbytag (tag)。

我知道这是一个老问题，但我分享了我找到的解决这个常见问题的最佳方案

        btnSomeButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            // Prevent Two Click
            Utils.preventTwoClick(view);
            // Do magic
        }
    });

在另一个文件中，比如Utils.java

    /**
 * Método para prevenir doble click en un elemento
 * @param view
 */
public static void preventTwoClick(final View view){
    view.setEnabled(false);
    view.postDelayed(
        ()-> view.setEnabled(true),
        500
    );
}

这个解决方案(Kotlin)对我很有效:

abstract class SingleClickListener : View.OnClickListener {
    private val MIN_CLICK_INTERVAL: Long = 1000
    private var mLastClickTime: Long = 0

    abstract fun onSingleClick(v: View?)

    override fun onClick(v: View?) {
        if (mLastClickTime <= 0) {
            mLastClickTime = SystemClock.uptimeMillis()
            onSingleClick(v)
            return
        }

        if (SystemClock.uptimeMillis() - mLastClickTime <= MIN_CLICK_INTERVAL) {
            return
        }

        mLastClickTime = SystemClock.uptimeMillis()

        onSingleClick(v)
    }
}

用法:

someView.setOnClickListener(object : SingleClickListener() {
    override fun onSingleClick(v: View?) {
        v?.also { klik(it) }
    }
})

或者也可以创建扩展函数，在视图上轻松添加ClickListener:

fun View.click(klik: (View) -> Unit) {
    this.setOnClickListener(object : SingleClickListener() {
        override fun onSingleClick(v: View?) {
            v?.also { klik(it) }
        }
    })
}

// Usage
class XPerimentActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_xperiment_layout)

        submit_button.click {
           // do your magic
        }
    }
}

我也遇到了类似的问题，我正在显示一些日期选择器和时间选择器，有时它会被点击2次。我用这个方法解决了这个问题:

long TIME = 1 * 1000;
@Override
public void onClick(final View v) {
v.setEnabled(false);
    
    new Handler().postDelayed(new Runnable() {

        @Override
        public void run() {
            v.setEnabled(true);
        }
    }, TIME);
}

你可以根据自己的需要改变时间。

在点击的时候保存最后一次点击的时间可以避免这个问题。

i.e.

private long mLastClickTime = 0;

...

// inside onCreate or so:

findViewById(R.id.button).setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        // mis-clicking prevention, using threshold of 1000 ms
        if (SystemClock.elapsedRealtime() - mLastClickTime < 1000){
            return;
        }
        mLastClickTime = SystemClock.elapsedRealtime();

        // do your magic here
    }
}

Setting the button as clickable false upon clicking and true once it is desired to make the button clickable again is the right approach. For instance, consider the following scenario: you are making a service call upon click of a button and once the service is done you want to display a dialog. For this, once the button is clicked you can set setClickable(false) and once the service responds you will do setClicklable(true) through a reference you pass to your custom dialog. When dialog invokes isShowing() you can trigger the listener and setClicklable(true).
