我创建了一个包含多个项目的listview，并在这些项目上添加了边框，因此它看起来像这样:
由于此自定义边框，项目的原始眨眼被阻止，因此它不会出现，并且我尝试通过动画添加眨眼，但是在主线程上有太多的延迟和太多的工作，我也使用了动画内线程，但它与延迟是一样的，这迫使我忘记动画，所以无论如何，我可以使该项目在单击时闪烁，而无需使用动画或不使用动画，但是我可以通过一种有效的方式来实现。我的onItemClickListener中使用了眨眼动画，您可以在下面的代码中找到它:
处理眨眼的onItemClickListener:
dataList.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, final View arg1,
final int arg2, long arg3) {
// TODO Auto-generated method stub
tvWarningNoEmp.setVisibility(View.GONE);
// adding blink
final Animation animation = new AlphaAnimation(
1, 0); // Change
// alpha
// from
// fully
// visible
// to
// invisible
animation.setDuration(100); // duration - half a
// second
animation
.setInterpolator(new LinearInterpolator()); // do
// not
// alter
// animation
// rate
animation.setRepeatCount(Animation.INFINITE); // Repeat
// animation
// infinitely
animation.setRepeatMode(Animation.REVERSE);
arg1.startAnimation(animation);
// blink one time timer
new CountDownTimer(100, 100) {// CountDownTimer(edittext1.getText()+edittext2.getText())
// also parse it to long
public void onTick(long millisUntilFinished) {
// here you can have your logic to set text to
// edittext
}
public void onFinish() {
arg1.clearAnimation();
}
}.start();
// set margins for tickets buttons
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
params.setMargins(0, 0, 30, 0);
bAssign.setLayoutParams(params);
LinearLayout.LayoutParams paramsO = new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
paramsO.setMargins(110, 0, 0, 0);
bEmpChat.setLayoutParams(paramsO);
noEmpLayout.setVisibility(LinearLayout.GONE);
empLayout.setVisibility(LinearLayout.VISIBLE);
Employee item = adapter.getItem(arg2);
ivEmpIcon.setBackgroundResource(R.drawable.free);
tvEmpName.setText(" " + item.getEmpName());
tvEmpDetails.setText(" " + item.getEmpDetails());
empLongitude = item.getEmpLongitude();
empLatitude = item.getEmpLatitude();
CameraPosition cameraPosition = new CameraPosition.Builder()
.target(new LatLng(empLatitude, empLongitude))
.zoom(15).build();
googleEmpMap.animateCamera(CameraUpdateFactory
.newCameraPosition(cameraPosition));
MarkerOptions marker = new MarkerOptions().position(
new LatLng(empLatitude, empLongitude)).title(
tvEmpName.getText().toString());
marker.icon(BitmapDescriptorFactory
.defaultMarker(BitmapDescriptorFactory.HUE_RED));
googleEmpMap.addMarker(marker);
// based on item add info to intent
// hide button directions
bEmpDirections.setVisibility(View.GONE);
// current address
Geocoder geocoder;
List<Address> addresses;
geocoder = new Geocoder(getApplicationContext(), Locale
.getDefault());
try {
addresses = geocoder.getFromLocation(empLatitude,
empLongitude, 1);
String street = addresses.get(0).getAddressLine(0);
String state = addresses.get(0).getAdminArea();
String country = addresses.get(0).getCountryName();
tvEmpCurrentAdd.setText(" " + country + "-" + state
+ "-" + street + " st.");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();}
}
});

最佳答案
如果您希望 View 闪烁:
public void blink(final View v) {
v.setBackgroundColor(Color.DKGRAY);
v.animate().setDuration(25).alpha(0).withEndAction(new Runnable() {
@Override
public void run() {
v.setBackgroundResource(R.drawable.standard_key_normal);
v.setAlpha(1);
}
});
}
将您的 View 发送到此功能，用所需的任何可绘制或彩色资源替换背景。如果要多次闪烁，请将其放入for循环中。
