<一>设置全屏
1、在onCreat方法中setContentView（）之前插入requestWindowFeature(Window.FEATURE_NO_TITLE);//取消标题栏
getWindow().setFlags(WindowManager.LayoutParams. FLAG_FULLSCREEN ,WindowManager.LayoutParams. FLAG_FULLSCREEN);//取消状态栏
注：这种方法在启动activity时会闪现状态栏之后再全屏
2、在manifest里面配置：<activity android:theme="@android:style/Theme.NoTitleBar.Fullscreen" />只在当前Activity内显示全屏
<application android:theme="@android:style/Theme.NoTitleBar.Fullscreen" />为整个应用配置全屏显示
3、/** * 全屏切换 */
public void fullScreenChange() {
SharedPreferences mPreferences = PreferenceManager.getDefaultSharedPreferences(this);
boolean fullScreen = mPreferences.getBoolean("fullScreen", false);
WindowManager.LayoutParams attrs = getWindow().getAttributes();
System.out.println("fullScreen的值:" + fullScreen);
if (fullScreen) {
attrs.flags &= (~WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().setAttributes(attrs);
//取消全屏设置
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
mPreferences.edit().putBoolean("fullScreen", false).commit() ;
} else {
attrs.flags |= WindowManager.LayoutParams.FLAG_FULLSCREEN;
getWindow().setAttributes(attrs);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
mPreferences.edit().putBoolean("fullScreen", true).commit();
}
}
<二>Activity之间跳转传值
采用Intent
MainActivity
Intent in = new Intent(MainActivity.this,ToActivity.class);
Bundle Bu = new Bundle();//传多值的载体
Bu.putString("Name", str);
in.putExtras(Bu);
startActivity(in);
ToActivity
Bundle bundle = this.getIntent().getExtras();
T2=(TextView)findViewById(R.id.helloview);
/*获取Bundle中的数据，注意类型和key*/
String name = bundle.getString("Name");
<三>TabHost
TabHost tabHost = (TabHost) findViewById(R.id.tabhost);
tabHost.setup();
tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("Tab1").setContent(R.id.view1));
tabHost.addTab(tabHost.newTabSpec("tab2").setIndicator("Tab2").setContent(R.id.view2));
tabHost.addTab(tabHost.newTabSpec("tab3").setIndicator("Tab3").setContent(R.id.view3));
