如何在RelativeLayout Android中设置LinearLayoutPosition

我要发疯了，想把我的直线布局变成一个相对的布局

下面是我的类和xml文件：

package com.example.layoutprova;

import android.app.Activity; 
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.RelativeLayout;

public class MainActivity extends Activity implements OnClickListener{

private CustomView mCustomView;
private Button mButton1;
private RelativeLayout mRelativeLayout;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mRelativeLayout = (RelativeLayout) findViewById(R.id.mainlayout);
    mButton1 = (Button) findViewById(R.id.button1);
    mButton1.setOnClickListener(this);
    mCustomView = new CustomView(this);
    mRelativeLayout.addView(mCustomView);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
    int buttonPressedId = v.getId();

    switch (buttonPressedId) {
    case R.id.button1: {
        mCustomView.setText("Change test");
        break;
    }
    default: {
        break;
    }
    }
}

}

其xml：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/mainlayout"
    android:layout_width="match_parent"

我想把我的CustomView放在MainActivity的右下角

谢谢

您正在寻找layoutParamsGreat，它可以完美地工作。我错了，因为我在XML文件中设置了param选项，但它们没有被读取。
