Android 部分機型沒有物理按鍵，只有虛擬按鍵，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、當用戶劃出虛擬按鍵后，自動再隱藏方法如下：
getWindow().getDecorView().setOnSystemUiVisibilityChangeListener(new OnSystemUiVisibilityChangeListener() { @Override public void onSystemUiVisibilityChange(int visibility) { int uiOptions = View.SYSTEM_UI_FLAG_LAYOUT_STABLE | //布局位于狀態(tài)欄下方 View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION | //全屏 View.SYSTEM_UI_FLAG_FULLSCREEN | //隱藏導航欄 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 隱藏方法
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 | //布局位于狀態(tài)欄下方 View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION | //全屏 View.SYSTEM_UI_FLAG_FULLSCREEN | //隱藏導航欄 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。以上這篇Android dialog 去除虛擬按鍵的解決方法就是小編分享給大家的全部內容了，希望能給大家一個參考，也希望大家多多支持武林網(wǎng)。
