Android，全屏全局方法

Question

所以我想让这 3 行作为我应用程序中每个 activity 的函数可用。我试图用这 3 行做一个简单的 MyMethods class 和一个 public void，但我没有工作（无法解析方法）

package com.example.myapplication;
import android.content.Intent;
import android.content.pm.ActivityInfo;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.view.Window;
import android.view.WindowManager;
import android.widget.EditText;

public class MainActivity extends AppCompatActivity {

public static final String EXTRA_MESSAGE = "com.example.myfirstapp.MESSAGE";

@Override
protected void onCreate(Bundle savedInstanceState) {

    //landscape,fullscreen,no action bar

    this.requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

    //I want those 3 lines above to be one void function 

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


}


public void sendMessage(View view){
    Intent intent = new Intent(this, DisplayMessageActivity.class);
    EditText editText = (EditText) findViewById(R.id.editText);
    String message = editText.getText().toString();
    intent.putExtra(EXTRA_MESSAGE, message);
    startActivity(intent);
}

}

Answer 1

试试这个方法，

 public class MyMethods extends AppCompatActivity  
 {
    @Override
    protected void onCreate(Bundle savedInstanceState) 
    {
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
        super.onCreate(savedInstanceState); 

    }

  }

现在 extends 这个在你的 MainActivity class

public class MainActivity extends MyMethods {

如果您使用 java 代码，则不推荐这样做。让 activity 全屏显示的更好方法是通过 activity 主题。

<style name="Theme.AppCompat.Light.NoActionBar.FullScreen" parent="@style/Theme.AppCompat.Light">
    <item name="windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowContentOverlay">@null</item>
</style>

并把它送给每一个 activity 想要全屏显示的人。

<activity
   android:name=".activities.MyFullScreenActivity"
   android:theme="@style/Theme.AppCompat.Light.NoActionBar.FullScreen" 
/>

希望它能奏效...:)
