1.MyDialog代码:
java
public class MyDialog{
private Activity activity;
private ViewGroup contentView;
private View view;
public MyDialog(Activity activity) {
this.activity=activity;
contentView = activity.findViewById(android.R.id.content);
view=LayoutInflater.from(activity).inflate(R.layout.dialog_layout,null);
view.findViewById(R.id.tv_cancel).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dismiss();
}
});
view.findViewById(R.id.tv_sure).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dismiss();
}
});
}
/**
* 显示dialog(包含动画)
*/
public void show(){
Animation animation= AnimationUtils.loadAnimation(activity,R.anim.dialog_in_anim);
view.setAnimation(animation);
contentView.addView(view);
}
/**
* 移除dialog(包含动画)
*/
public void dismiss(){
Animation animation= AnimationUtils.loadAnimation(activity,R.anim.dialog_out_anim);
view.setAnimation(animation);
contentView.removeView(view);
}
}
2.res/anim 下新建 dialog_in_anim.xml 和 dialog_out_anim.xml
dialog_in_anim.xml 底部显示
XML
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="300"
android:fromYDelta="100%p"
android:toYDelta="0%p" />
</set>
dialog_out_anim.xml 底部隐藏
XML
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="300"
android:fromYDelta="0%p"
android:toYDelta="100%p" />
</set>
3.界面布局:dialog_layout.xml ,半透明颜色值:#80000000
XML
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#80000000">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:background="@android:color/white"
android:orientation="vertical"
android:paddingStart="40dp"
android:paddingTop="20dp"
android:paddingEnd="40dp"
android:paddingBottom="20dp">

android:layout_marginBottom="30dp"
android:text="标题"

/>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginStart="30dp"
android:orientation="horizontal">
<TextView
