LayoutInflater 之Demo

LayoutInflater的使用效果和findViewById()有点类似，不过它有更多的功能，具体可以参考api;

 

代码：

 

}else if(v.getId()==R.id.dialog_Button){
			LayoutInflater inflater = (LayoutInflater) MyGridActivity.this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
			View layout = inflater.inflate(R.layout.main_item, null);
			EditText txt = (EditText) layout.findViewById(R.id.dia_txt);
			txt.setText("Dialog");
			Button btn  =(Button) layout.findViewById(R.id.dia_btn);
			ImageView img = (ImageView) layout.findViewById(R.id.dia_image);
			img.setImageResource(R.drawable.super_btn_png1);
			Builder builder = new AlertDialog.Builder(MyGridActivity.this);
			builder.setView(layout);
			AlertDialog dialog = builder.create();
			dialog.show();
			btn.setOnClickListener(new OnClickListener(){
				@Override
				public void onClick(View arg0) {
					// TODO Auto-generated method stub
					/**
					 * 
					 * 
					 */
				}
			});

 

dialog_xml：

 

<?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="wrap_content"
    android:paddingBottom="4dip" >

    <ImageView
        android:id="@+id/dia_image"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true" />

    <Button
        android:id="@+id/dia_btn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/dia_image"
        android:layout_marginRight="40dp"
        android:layout_marginTop="131dp"
        android:layout_toLeftOf="@+id/dia_image"
        android:text="Button" />

    <EditText
        android:id="@+id/dia_txt"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true" >

        <requestFocus />
    </EditText>

</RelativeLayout>

 

效果：
