Android 動態切換全屏和非全屏模式

 代碼示例：

package com.screen;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.WindowManager;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivity extends Activity {

    private boolean isFulllScreen = false;
    private Button button;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        button = (Button)findViewById(R.id.button);
        button.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                isFulllScreen = !isFulllScreen;
                if (isFulllScreen) {
                    button.setText(getResources().getText(R.string.exit_full_screen));
                    WindowManager.LayoutParams params = getWindow().getAttributes();
                    params.flags |= WindowManager.LayoutParams.FLAG_FULLSCREEN;
                    getWindow().setAttributes(params);
                    getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
                } else {
                    button.setText(getResources().getText(R.string.full_screen));
                    WindowManager.LayoutParams params = getWindow().getAttributes();
                    params.flags &= (~WindowManager.LayoutParams.FLAG_FULLSCREEN);
                    getWindow().setAttributes(params);
                    getWindow().clearFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
                }
            }
        });

    }
}
