点击后如何临时更改Android按钮样式?
How to change Android button style temporarily after click?
请建议我一些好的做法来更改按钮背景颜色 onclick(几秒钟)。我用 Android API 22.
几天前我遇到了类似的问题,请随意使用我的代码。
Button myButton; //as a "global" variable so that it is also recognized in the onClick event.
myButton = (Button) findViewById(R.id.b)
myButton.setBackgroundColor(Color.BLACK); //set the color to black
myButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
myButton.setBackgroundColor(Color.RED); //set the color to red
// Delay of 2 seconds (200 ms) before changing back the color to black
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
@Override
public void run() {
myButton.setBackgroundColor(Color.BLACK); //set the color to black
}
}, 200);
}
}
虽然我不知道这是否被认为是好的做法...
祝你有愉快的一天!
我为 Android API 21 提出了这个解决方案:
@Override
public void onClick(final View view) {
final int redColor = 0xFFFF0000;
view.getBackground().setColorFilter(redColor, PorterDuff.Mode.MULTIPLY);
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
@Override
public void run() {
view.getBackground().clearColorFilter();
}
}, 700);
}
