Android Launcher如何去掉进入应用时的动画效果

Answer 1

请修改Launcher.java的startActivity方法，如下：
boolean startActivity(View v, Intent intent, Object tag) {
if (LauncherLog.DEBUG) {
LauncherLog.d(TAG, "startActivity v = " + v + ", intent = " + intent + ", tag = " + tag);
}
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
try {
// Only launch using the new animation if the shortcut has not opted out (this is a
// private contract between launcher and may be ignored in the future).
//boolean useLaunchAnimation = (v != null) && //mtk modify
// !intent.hasExtra(INTENT_EXTRA_IGNORE_LAUNCH_ANIMATION); //mtk modify
boolean useLaunchAnimation = false; //mtk add
/// M: add systrace to analyze application launche time.
Trace.traceBegin(Trace.TRACE_TAG_INPUT, "Launcher.startActivity");
if (useLaunchAnimation) {
ActivityOptions opts = ActivityOptions.makeScaleUpAnimation(v, 0, 0,
v.getMeasuredWidth(), v.getMeasuredHeight());
startActivity(intent, opts.toBundle());
} else {
startActivity(intent);
}
/// M: add systrace to analyze application launche time.
Trace.traceEnd(Trace.TRACE_TAG_INPUT);
return true;
} catch (SecurityException e) {
Toast.makeText(this, R.string.activity_not_found, Toast.LENGTH_SHORT).show();
Log.e(TAG, "Launcher does not have the permission to launch " + intent +
". Make sure to create a MAIN intent-filter for the corresponding activity " +
"or use the exported attribute for this activity. "
+ "tag=" + tag + " intent=" + intent, e);
}
return false;
}
