给所有的activity设置全屏布局

Question

我想做出一个适合所有智能手机的全屏模式。下面这段代码创建一个tablelayout布局，可以水平和垂直滚动。同时想把 edittext矩阵集放在布局的中间位置。怎么实现这个功能？

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.seconda);

HorizontalScrollView HSC = new HorizontalScrollView(this);
ScrollView VSC = new ScrollView(this);
VSC.setBackgroundResource(R.drawable.lavagna_psd);

tableLayout = new TableLayout(this);
tableLayout.setGravity(Gravity.CENTER); 

values = new EditText[3][3];

for (int i = 0; i < 3; i++) {

tableRow = new TableRow(this); 
tableRow.setGravity(Gravity.CENTER);

for (int j = 0; j < 3  ; j++) {
values[i][j] = new EditText(this);
values[i][j].setHint("r: " + (i) + " " + "c: " + (j));
values[i][j].setPadding(10, 10, 10, 10);
tableRow.addView(values[i][j]);
}

tableLayout.addView(tableRow);
}
VSC.addView(tableLayout);
HSC.addView(VSC);
setContentView(HSC);

}

你可以在xml配置或java代码中设置全屏
在目录res/values下创建自定义的styles.xml。

<style name="Theme.CustomizedFullScreen" parent="android:Theme">
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowNoTitle">true</item>
</style>

在 menifest文件中

android:theme="@style/Theme.CustomizedFullScreen"

onCreate()创建后，在activity的java文件中也可以这样创建

requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
        WindowManager.LayoutParams.FLAG_FULLSCREEN);
