Android常用语句收集

一、弹出窗口

new AlertDialog.Builder(DialogTestActivity.this).setMessage("是否关闭").setTitle("提示:").setPositiveButton("确定", new DialogInterface.OnClickListener() {public void onClick(DialogInterface dialog, int which) {finish();}}).setNegativeButton("取消", null).show();



二、实现抖动效果

实现抖动是采用的Animation动画在res下新建anim文件夹,然后创建shake.xml和cycle_interpolator.xml文件,文件内容分别如下
shake.xml

<translate xmlns:android="http://schemas.android.com/apk/res/android"    android:duration="400"    android:fromXDelta="0"    android:interpolator="@anim/cycle_interpolator"    android:toXDelta="8" />

cycle_interpolator.xml
<cycleInterpolator xmlns:android="http://schemas.android.com/apk/res/android"    android:cycles="3" />

布局文件main.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="horizontal" >    <EditText        android:id="@+id/editText1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="点击按钮测试是否抖动" >    </EditText>    <Button        android:id="@+id/but"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="点击" /></LinearLayout>

Activiy文件
public class DialogTestActivity extends Activity {private  Button button ;private  EditText text;private  Animation animation;@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);button = (Button) findViewById(R.id.but);text = (EditText)findViewById(R.id.editText1);animation = AnimationUtils.loadAnimation(this, R.anim.shake);button.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {text.startAnimation(animation);}});}}
