框架布局管理器FrameLayout

 

main.xml

换了一个布局管理器
      xmlns:android="
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >
            android:id="@+id/mying"
        android:src="@drawable/fish"
        android:layout_width = "wrap_content"
        android:layout_height= "wrap_content"/>
          android:id="@+id/myinput"
        android:text="请输入姓名"
        android:layout_width = "wrap_content"/>
            android:id="@+id/mybut"
        android:layout_width = "wrap_content"
        android:layout_height= "wrap_content"
          android:text="按我" /> 

    

 

 

通过activity定义framelayout(与main.xml无关)

package your.packfage.namespace;

import android.app.Activity;
import android.os.Bundle;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.EditText;
import android.widget.FrameLayout;
import android.widget.ImageView;

public class FrameLayoutActivity extends Activity
{
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        FrameLayout layout = new FrameLayout(this);//定义帧布局管理器
        FrameLayout.LayoutParams layoutParam= new FrameLayout.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT,ViewGroup.LayoutParams.FILL_PARENT) ;//定义布局管理器参数
        FrameLayout.LayoutParams viewParam= new FrameLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,ViewGroup.LayoutParams.WRAP_CONTENT) ;//定义显示组件参数
        ImageView img = new ImageView(this) ;//定义图片组件
        img.setImageResource(R.drawable.fish);
        EditText edit = new EditText(this) ;
        edit.setText("请输入姓名") ;
        Button but = new Button(this) ;
         but.setText("按我");
         layout.addView(img,viewParam);
         layout.addView(edit,viewParam);
         layout.addView(but,viewParam);
         super.setContentView(layout,layoutParam) ;//向屏幕上增加布局管理器
        setContentView(R.layout.main);
    }
}
