[置顶] Android Activity 淡入淡出和从底部向上弹出动画效果

动画效果Activity淡入，同按钮布局有屏幕底部向上推出，代码比较简单就不在这里详细介绍。

 

1.首先创建一个，的布局文件clearpan.xml，这个文件就是从下到上弹出的布局文件。
    

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

android:orientation="vertical" >
<!-- android:background="@drawable/clearpanbackground" -->

<RelativeLayout
android:id="@+id/clearallpan"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="@drawable/incall_bg"
>

<Button
android:id="@+id/clearall"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="10dip"
android:layout_marginRight="10dip"
android:layout_marginTop="20dip"
android:layout_marginBottom="10dip"
android:background="@drawable/iphonesms_smsdetail_delete_deleteall"
android:text="删除所有"
android:textColor="#FFFFFFFF"/>

<Button
android:id="@+id/cancel"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="10dip"
android:layout_marginRight="10dip"
android:layout_marginTop="10dip"
android:layout_marginBottom="20dip"

android:text="取消"
android:background="@drawable/iphonesms_smsdetail_delete_forwardall"
android:layout_below="@id/clearall"
android:textColor="#FFFFFFFF"/>

</RelativeLayout>

</RelativeLayout>
2.在anim文件夹下，定义动画效果文件
<?xml version="1.0" encoding="utf-8"?>

<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/accelerate_interpolator" >
<translate
android:duration="300"
android:fromYDelta="100.0%"
android:toYDelta="10.000002%" />
<alpha
android:duration="50"
android:fromAlpha="0.0"
android:toAlpha="1.0" />
</set>

3 .创建AnimationActivity.Java代码类。
public class AnimationActivity extends Activity {
private Button mBtu;
private String mStr;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mBtu = (Button) findViewById(R.id.clear);
mBtu.setOnClickListener(new OnClickListener() {
private AlertDialog dlg = null;

Button mCancelBtn = null;
Button mClearAllBtn = null;

@Override
public void onClick(View v) {
this.dlg = new AlertDialog.Builder(AnimationActivity.this)
.create();
View localView = AnimationActivity.this.getLayoutInflater()
.inflate(R.layout.clearpan, null);
localView.setAnimation(AnimationUtils.loadAnimation(
AnimationActivity.this, R.anim.slide_bottom_to_top));
Window localWindow = this.dlg.getWindow();
localWindow.getAttributes();
this.dlg.show();
localWindow.setContentView(localView);
localWindow.setGravity(Gravity.BOTTOM);
localWindow.setLayout(-1, 280);
this.mClearAllBtn = ((Button) this.dlg
.findViewById(R.id.clearall));
this.mCancelBtn = ((Button) this.dlg
.findViewById(R.id.cancel));
this.mClearAllBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View paramView) {
finish();
}
});

this.mCancelBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View paramView) {
dlg.cancel();
}
});
}

});

}
}
