這篇文章將為大家詳細講解有關Android應用怎么實現隱藏狀態欄,文章內容質量較高,因此小編分享給大家做個參考,希望大家閱讀完這篇文章后對相關知識有一定的了解。
方法一:
public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // 隱藏標題欄 requestWindowFeature(Window.FEATURE_NO_TITLE); // 隱藏狀態欄 getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); setContentView(R.layout.activity_main); } }
方法二:
<!-- 同時隱藏狀態欄和標題欄 --> <activity android:name="com.ysj.demo.MainActivity" android:theme="@android:style/Theme.NoTitleBar.Fullscreen" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity>
方法三:
<!-- Application theme. --> <style name="AppTheme" parent="AppBaseTheme"> <!-- All customizations that are NOT specific to a particular API-level can go here. --> <!-- 隱藏狀態欄 --> <item name="android:windowFullscreen">true</item> <!-- 隱藏標題欄 --> <item name="android:windowNoTitle">true</item> </style>
方法四:動態顯示隱藏狀態欄
//隱藏狀態欄 WindowManager.LayoutParams lp = context.getWindow().getAttributes(); lp.flags |= WindowManager.LayoutParams.FLAG_FULLSCREEN; context.getWindow().setAttributes(lp); //顯示狀態欄 WindowManager.LayoutParams attr = context.getWindow().getAttributes(); attr.flags &= (~WindowManager.LayoutParams.FLAG_FULLSCREEN); context.getWindow().setAttributes(attr);
方法五:動態顯示隱藏狀態欄
View類提供了setSystemUiVisibility和getSystemUiVisibility方法,這兩個方法實現對狀態欄的動態顯示或隱藏的操作,以及獲取狀態欄當前可見性。
setSystemUiVisibility方法傳入的實參分析:
setSystemUiVisibility(int visibility)方法可傳入的實參為:
1. View.SYSTEM_UI_FLAG_VISIBLE:顯示狀態欄,
Activity不全屏顯示(恢復到有狀態的正常情況)。
2. View.INVISIBLE:隱藏狀態欄,同時Activity會伸展全屏顯示。
3. View.SYSTEM_UI_FLAG_FULLSCREEN:Activity全屏顯示,且狀態欄被隱藏覆蓋掉。
4. View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN:Activity全屏顯示,但狀態欄不會被隱藏覆蓋,狀態欄依然可見,Activity頂端布局部分會被狀態遮住。
5. View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION:效果同View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
6. View.SYSTEM_UI_LAYOUT_FLAGS:效果同View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
7. View.SYSTEM_UI_FLAG_HIDE_NAVIGATION:隱藏虛擬按鍵(導航欄)。有些手機會用虛擬按鍵來代替物理按鍵。
8. View.SYSTEM_UI_FLAG_LOW_PROFILE:狀態欄顯示處于低能顯示狀態(low profile模式),狀態欄上一些圖標顯示會被隱藏。
package com.administrator.statubarapplication; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.LinearLayout; import android.widget.TextView; public class MainActivity extends Activity implements View.OnClickListener { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); assignViews(); setOnClicks(); } private void setOnClicks() { mButton1.setOnClickListener(this); mButton2.setOnClickListener(this); mButton3.setOnClickListener(this); mButton4.setOnClickListener(this); mButton5.setOnClickListener(this); mButton6.setOnClickListener(this); mButton7.setOnClickListener(this); } private LinearLayout mMain; private TextView mTextview; private Button mButton1; private Button mButton2; private Button mButton3; private Button mButton4; private Button mButton5; private Button mButton6; private Button mButton7; private void assignViews() { mMain = (LinearLayout) findViewById(R.id.main); mTextview = (TextView) findViewById(R.id.textview); mButton1 = (Button) findViewById(R.id.button1); mButton2 = (Button) findViewById(R.id.button2); mButton3 = (Button) findViewById(R.id.button3); mButton4 = (Button) findViewById(R.id.button4); mButton5 = (Button) findViewById(R.id.button5); mButton6 = (Button) findViewById(R.id.button6); mButton7 = (Button) findViewById(R.id.button7); } @Override public void onClick(View v) { switch (v.getId()) { case R.id.button1: //Activity全屏顯示,且狀態欄被隱藏覆蓋掉 mMain.setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN); mTextview.setText("Activity全屏顯示,且狀態欄被隱藏覆蓋掉\nView.SYSTEM_UI_FLAG_FULLSCREEN"); break; case R.id.button2: mMain.setSystemUiVisibility(View.SYSTEM_UI_FLAG_VISIBLE); mTextview.setText("恢復到有狀態的正常情況\nView.SYSTEM_UI_FLAG_VISIBLE"); break; case R.id.button3: mMain.setSystemUiVisibility(View.INVISIBLE); mTextview.setText("//隱藏狀態欄,同時Activity會伸展全屏顯示\nView.INVISIBLE"); break; case R.id.button4: mMain.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN); mTextview.setText("Activity全屏顯示,但狀態欄不會被隱藏覆蓋,狀態欄依然可見,Activity頂端布局部分會被狀態遮\nView" + ".SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN \n View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION"); break; case R.id.button5: mMain.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN); mTextview.setText("Activity全屏顯示,狀態欄透明\nView.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION"); break; case R.id.button6: mMain.setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION); mTextview.setText("隱藏虛擬按鍵\nView.SYSTEM_UI_FLAG_HIDE_NAVIGATION"); break; case R.id.button7: mMain.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE); mTextview.setText("狀態欄低能顯示,有一些會被隱藏\nView.SYSTEM_UI_FLAG_LOW_PROFILE"); break; default: break; } } }
下面看下 隱藏標題欄和底部操作欄,可上下滑動顯示代碼
@Override public void onWindowFocusChanged(boolean hasFocus) { super.onWindowFocusChanged(hasFocus); if (hasFocus) { View decorView = that.getWindow().getDecorView(); decorView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY | View.SYSTEM_UI_FLAG_FULLSCREEN); } }
