Android 部分机型没有物理按键，只有虚拟按键，Activity全屏方法如下：
1、在
setContentView(R.layout.activity_main);之前添加
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
2、当用户划出虚拟按键后，自动再隐藏方法如下：
getWindow().getDecorView().setOnSystemUiVisibilityChangeListener(new OnSystemUiVisibilityChangeListener() {
@Override
public void onSystemUiVisibilityChange(int visibility) {
int uiOptions = View.SYSTEM_UI_FLAG_LAYOUT_STABLE |
//布局位于状态栏下方
View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION |
//全屏
View.SYSTEM_UI_FLAG_FULLSCREEN |
//隐藏导航栏
View.SYSTEM_UI_FLAG_HIDE_NAVIGATION |
View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN;
if (Build.VERSION.SDK_INT >= 19) {
uiOptions |= 0x00001000;
} else {
uiOptions |= View.SYSTEM_UI_FLAG_LOW_PROFILE;
}
getWindow().getDecorView().setSystemUiVisibility(uiOptions);
}
});
3、dialog 隐藏方法
mDialog.getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
mDialog.getWindow().getDecorView().setOnSystemUiVisibilityChangeListener(new OnSystemUiVisibilityChangeListener() {
@Override
public void onSystemUiVisibilityChange(int visibility) {
int uiOptions = View.SYSTEM_UI_FLAG_LAYOUT_STABLE |
//布局位于状态栏下方
View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION |
//全屏
View.SYSTEM_UI_FLAG_FULLSCREEN |
//隐藏导航栏
View.SYSTEM_UI_FLAG_HIDE_NAVIGATION |
View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN;
if (Build.VERSION.SDK_INT >= 19) {
uiOptions |= 0x00001000;
} else {
uiOptions |= View.SYSTEM_UI_FLAG_LOW_PROFILE;
}
mDialog.getWindow().getDecorView().setSystemUiVisibility(uiOptions);
}
});要在mDialog.show();之前。
