First, a custom dialog inherited from dialog
public class CustomDialog extends Dialog {
private Context c;
public CustomDialog(@NonNull Context context) {
super(context);

public CustomDialog(@NonNull Context context, int themeResId) {

this.setContentView(v);
this.setCancelable(true);
RecyclerView rv = v.findViewById(R.id.rv);
DialogAdapter adapter = new DialogAdapter(c, datas, new DialogRvListener() {
@Override
public void onItemClick(int pos) {
if (dialogListener!=null){

//窗口位置
setWindow(getWindow());
}
/***

//窗口位置
setWindow(getWindow());
}
/***

*/
public void init(String[]datas,int viewId,final DialogListener dialogListener){
LinearLayout v = new LinearLayout(c);
v.setOrientation(LinearLayout.VERTICAL);
//自定义标题
View titleView = LayoutInflater.from(c).inflate(viewId,null);
LinearLayout.LayoutParams header_params = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.WRAP_CONTENT);

//列表

rv.setId(R.id.rv);
LinearLayout.LayoutParams rv_params = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.WRAP_CONTENT);
v.addView(rv,rv_params);
this.setContentView(v);
this.setCancelable(true);
//窗口位置
setWindow(getWindow());
}
/**
* 设置窗口位置
*/
private void setWindow(Window wd){
if (wd==null){
return;
}
WindowManager.LayoutParams params = wd.getAttributes();
params.width = WindowManager.LayoutParams.MATCH_PARENT;
params.height = WindowManager.LayoutParams.WRAP_CONTENT;
wd.setAttributes(params);
wd.setGravity(Gravity.BOTTOM);
}
/**

*/
public void setAnim(int styleId){

if (w==null){

}
dialog layout file (here only show no title bar)
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:id="@+id/ll"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<android.support.v7.widget.RecyclerView
android:id="@+id/rv"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</LinearLayout>
dialog in the adapter used recyclerview
public class DialogAdapter extends RecyclerView.Adapter<DialogAdapter.DialogViewHolder> {
private String[]datas;
private DialogRvListener dialogRvListener;
private Context c;
DialogAdapter(Context c, String[] datas, DialogRvListener dialogRvListener){
this.c = c;
this.datas = datas;
this.dialogRvListener = dialogRvListener;
}
@NonNull
@Override
public DialogViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
View v = LayoutInflater.from(c).inflate(R.layout.item_dialog,viewGroup,false);
return new DialogViewHolder(v);
}
@Override
public void onBindViewHolder(@NonNull DialogViewHolder holder, final int i) {
holder.tv.setText(datas[i]);
holder.tv.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dialogRvListener.onItemClick(i);
}
});
}
@Override
public int getItemCount() {
return datas.length;
}
class DialogViewHolder extends RecyclerView.ViewHolder{
TextView tv;
DialogViewHolder(@NonNull View itemView) {
super(itemView);
tv = itemView.findViewById(R.id.tv);
}
}
}
recyclerview item in the layout file is actually a textview
<?xml version="1.0" encoding="utf-8"?>
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="15sp"
android:textColor="@android:color/black"
android:text="123"
android:gravity="center"
android:paddingTop="10dp"
android:paddingBottom="10dp"
android:id="@+id/tv"/>
Two locations interfaces, in fact, the method is the same, but in order to distinguish between two write:
Dialog Listener
void onItemClick(int pos);
DialogRvListener
void onItemClick(int pos);
In this way, a basic custom dialog is complete, just call in to the activity
//带标题，同时自定义风格（这样可以保证宽度占满屏幕）
CustomDialog titledialog = new CustomDialog(this,R.style.customdialog);
titledialog.init(datas, "请选择", new DialogListener() {
@Override
public void onItemClick(int pos) {
//your logic
}
});
//自定义动画
titledialog.setAnim(R.style.mydialog);
I have a good package and spread to github, it can be added directly dependent on use. If you feel good trouble spots like this one, you have any questions or good suggestions can leave a comment below.
