在Android中调用其他活动时如何避免黑屏? [英] How to avoid black screen while invoking another activity in android?

问题描述

我正在使用主要活动中的意图来调用活动.但是在调用过程中，很少显示系统对话框，因此会显示黑屏.我如何避免出现黑屏.

解决方案

请检查您在意图中设置的标志.

如果您有finish();或FLAG_ACTIVITY_CLEAR_TASK-ICS之前的设备上可能会出现黑屏，因为在开始另一个活动之前已清除了当前活动.

Intent intent = new Intent(getApplicationContext(), Activity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
overridePendingTransition (0, 0);

i am invoking an activity using intent from main activity. But during the invocation few system dialog boxes are displayed because of which a black screen is displayed. How can i avoid such black screen.

解决方案

Please check the flags you are setting in your intent.

If you have a finish(); or FLAG_ACTIVITY_CLEAR_TASK - a blank screen may show up on pre ICS devices as the current activity has been cleared before another activity is started.

Intent intent = new Intent(getApplicationContext(), Activity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
overridePendingTransition (0, 0);
