[android] 03_纯手工创建UI - Android 4.0 Documentation

特殊应用场景——手工编写可以精简R.java文件输入法的界面

1、代码：

package cn.zengfansheng.manualUI;

import android.app.Activity;

import android.graphics.Color;

import android.os.Bundle;

import android.view.ViewGroup.LayoutParams;

import android.view.WindowManager;

import android.widget.LinearLayout;

import android.widget.TextView;

public class MainActivity extends Activity {

@SuppressWarnings("deprecation")

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

WindowManager wm = (WindowManager) this.getSystemService(WINDOW_SERVICE);

int width = wm.getDefaultDisplay().getWidth() / 3;// 获取屏幕宽度/3

LinearLayout llLayout = new LinearLayout(this);

llLayout.setOrientation(LinearLayout.VERTICAL);// 设置线性布局的朝向

TextView tv1 = new TextView(this);

tv1.setText("内容1");

tv1.setBackgroundColor(Color.GREEN);

llLayout.addView(tv1, width,LayoutParams.WRAP_CONTENT);

TextView tv2 = new TextView(this);

tv2.setText("内容2");

tv2.setBackgroundColor(Color.GREEN);

llLayout.addView(tv2, width,LayoutParams.WRAP_CONTENT);

this.setContentView(llLayout);

}

2、结果：
