Android 振动点击

Vibrate onclick

提问by Rui Miranda

Is there a way to get a button to vibrate but only when the if condition is verified?

有没有办法让按钮振动，但只有在 if 条件得到验证时？

Here's the code:

这是代码：

Vibrator vibe = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE) ;

if(l2>=l1){
        insertactone.setBackgroundColor(Color.RED);

    };

here is the onclick method for insertactone:

这是 insertactone 的 onclick 方法：

einsertactone = (Button) findViewById(R.id.bsqlinsertactone);
    insertactone.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            switch (v.getId()) {
            case R.id.bsqlinsertactone:
                insertactoneClick();
                break;
            }
        }

        private void insertactoneClick() {
            startActivity(new Intent(
                    "com.example.everydaybudgetplanner.ACTONESQLENTRY"));
        }

    });

I want it to vibrate only if the the IF condition is verified.

我希望它仅在 IF 条件得到验证时振动。

Yes. It looks like you have 95% of the code there already. Where did you get stuck?

是的。看起来您已经拥有 95% 的代码。你在哪里卡住了？

You already have a VibratorObject and a conditional. All you need to do now is call vibrate()like so:

你已经有了一个Vibrator对象和一个条件。你现在需要做的就是vibrate()像这样调用：

Vibrator vibe = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);

if(l2 >= l1) {
    insertactone.setBackgroundColor(Color.RED);
    vibe.vibrate(100);
}

Don't forget that you need to add

不要忘记你需要添加

<uses-permission android:name="android.permission.VIBRATE" />

in your AndroidManifest.xml file.

在您的 AndroidManifest.xml 文件中。
