Android功能代码

安卓打开应用程序

打开设置主界面

Intent intent = new Intent(android.provider.Settings.ACTION_SETTINGS); //系统设置
startActivityForResult( intent , 0);

打开网络设置界面(其他设置中的界面同理)

Intent intent = new Intent(android.provider.Settings.ACTION_WIFI_SETTINGS);//WIFI设置
startActivity(intent);
Intent intent = new Intent(android.provider.Settings.ACTION_APPLICATION_SETTINGS);//管理应用程序界面
context.startActivity(intent);

或者用以下方法(3.0以前的版本可以用此方法)
Intent intent = new Intent("/");
ComponentName cm = new ComponentName("com.android.settings", "com.android.settings.WirelessSettings");
intent.setComponent(cm);
intent.setAction("android.intent.action.VIEW");
startActivityForResult( intent , 0);

打开壁纸设置

Intent intent = new Intent(Intent.ACTION_SET_WALLPAPER);
startActivity(intent);

打开拨号界面

Intent intent = new Intent(Intent.ACTION_DIAL);
startActivity(intent);

打开联系人界面

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setType("vnd.android.cursor.dir/contact");
startActivity(intent);

打开通话记录

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setType("vnd.android.cursor.dir/calls");
startActivity(intent);

打开短信列表界面

Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_DEFAULT);
intent.setType("vnd.android-dir/mms-sms");
startActivity(intent);

安卓音效代码

SoundPool soundPool;
int click;
soundPool = new SoundPool(3, AudioManager.STREAM_MUSIC, 0);
click = soundPool.load(GridViewTest.this, R.raw.click6, 1);
soundPool.play(click, 1, 1, 0, 0, 1);

创建对话框

final Builder builder = new AlertDialog.Builder(this);
// 为按钮绑定事件监听器

// 设置对话框的图标
builder.setIcon(R.drawable.icon);
// 设置对话框的标题
builder.setTitle("请您验证管理员信息");
// 装载/res/layout/login.xml界面布局

final TableLayout loginForm = (TableLayout) getLayoutInflater()
.inflate(R.layout.activity_super, null);

// 设置对话框显示的View对象
builder.setView(loginForm);
// 为对话框设置一个“确定”按钮
builder.setPositiveButton("验证"
// 为按钮设置监听器
, new OnClickListener()
{

@Override
public void onClick(DialogInterface dialog, int which)
{

// 为对话框设置一个“取消”按钮
builder.setNegativeButton("取消", new OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int which)
{

}
});
// 创建、并显示对话框
builder.create().show();
}

打开网页

Uri uri = Uri.parse("http://www.baidu.com");
Intent it = new Intent(Intent.ACTION_VIEW, uri);
startActivity(it);

单选对话框

oncreate()方法中：showDialog(SINGLE_DIALOG);

@Override
public Dialog onCreateDialog(int id, Bundle state)
{
// 判断需要生成哪种类型的对话框
switch (id)
{
case SINGLE_DIALOG:
Builder b = new AlertDialog.Builder(this);
// 设置对话框的图标
b.setIcon(R.drawable.icon);
// 设置对话框的标题
b.setTitle("请选择您要执行的操作");

// 为对话框设置多个列表
b.setItems(new String[] { "开始",,

}
// 为列表项的单击事件设置监听器
, new OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int which)
{

// which代表哪个列表项被单击了
switch (which)
{
case 0:

MyActivityManager.exit();

break;

}
}
});
// 添加一个“确定”按钮，用于关闭该对话框

return b.create();
}
return null;
}

动画代码

final Animation anim1 = AnimationUtils.loadAnimation(this,
R.anim.xuanzhuan);
final Handler myHandler = new Handler()
{
@Override
public void handleMessage(Message msg)
{
// 如果该消息是本程序所发送的
if (msg.what == 0x1233)
{
// 动态地修改所显示的图片

text.startAnimation(anim2);
if (currentImageId >= imageIds.length)
{
currentImageId = 0;
}
}
}
};
// 定义一个计时器，让该计时器周期性地执行指定任务
new Timer().schedule(new TimerTask()
{
@Override
public void run()
{
// 新启动的线程无法访问该Activity里的组件
// 所以需要通过Handler发送信息
Message msg = new Message();
msg.what = 0x1233;
// 发送消息
myHandler.sendMessage(msg);
}
}, 0, 2000);

键盘消失

InputMethodManager imm = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(v.getWindowToken(), 0);

截屏代码

String time = null;
public void shareScreenshot()
{
time = "rival_" + DateUtils.getTimeNow();
shot();
new Thread(new Runnable()
{
public void run()
{
Intent intent = new Intent("android.intent.action.SEND");

intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

// 分享图标
public void shareIcon()
{

/**

private Bitmap shot()
{
View view = getWindow().getDecorView();
Display display = this.getWindowManager().getDefaultDisplay();
view.layout(0, 0, display.getWidth(), display.getHeight());
view.setDrawingCacheEnabled(true);// 允许当前窗口保存缓存信息，这样getDrawingCache()方法才会返回一个Bitmap

Bitmap bmp = Bitmap.createBitmap(view.getDrawingCache());
view.destroyDrawingCache();
FileUtils.savePic(bmp, time);
return bmp;
}

进度条

ProgressDialog progressDialog;
progressDialog = ProgressDialog.show(
UserDeleteActivity.this, "正在注销", "请您稍后...",
false, true);

new Thread(new Runnable()
{

public void run()
{

try
{
Looper.prepare();

Message msg = new Message();
msg.arg1 = 0;
myhandler.sendMessage(msg);
}

}
connection.close();
}
catch (Exception e)
{
Message msg = new Message();

myhandler.sendMessage(msg);

}
finally
{
progressDialog.dismiss();

}

}

}).start();
Handler myhandler = new Handler()

@Override
public void handleMessage(Message msg)
{
super.handleMessage(msg);
if (msg.arg1 == 0)

{

progressDialog.dismiss();

Toast.LENGTH_SHORT).show();

}
else if (msg.arg1 == 2)
{

progressDialog.dismiss();

}

}

};

快捷方式

Intent addIntent = new Intent(
"com.android.launcher.action.INSTALL_SHORTCUT");
String title = getResources().getString(R.string.app_name);
// 加载快捷方式的图标
Parcelable icon = Intent.ShortcutIconResource.fromContext(
LoginActivity.this, R.drawable.icon);
// 创建点击快捷方式后操作Intent,该处当点击创建的快捷方式后，再次启动该程序
Intent myIntent = new Intent(LoginActivity.this,
com.nuc.smartcloud.extra.SplashscreenActivity.class);
// 设置快捷方式的标题
addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, title);
// 设置快捷方式的图标
addIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, icon);
// 设置快捷方式对应的Intent
addIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, myIntent);
// 发送广播添加快捷方式
sendBroadcast(addIntent);
