Android设置窗口变暗，圆角按钮以及include和merge的使用
昨天写了一个小Demo，实现了几个小功能，今天贴上来。由于这几个个Feature比较简单，所以放在一起了。先看一下效果图：
上代码：
Main：
package com.example.includelayoutdemo;
import android.app.Activity;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.Window;
import android.view.WindowManager;
import android.widget.Button;
import android.widget.Toast;
public class Main extends Activity {
private Button btnSet;
private Button btnCancel;
private WindowManager.LayoutParams layoutParams;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
btnSet = (Button) findViewById(R.id.btnSet);
btnCancel = (Button) findViewById(R.id.btnCancel);
btnSet.setOnClickListener(new onClickListenerImp());
btnCancel.setOnClickListener(new onClickListenerImp());
layoutParams = getWindow().getAttributes();
}
class onClickListenerImp implements OnClickListener {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if (v == btnSet) {
// 将窗口变暗处理
layoutParams.dimAmount = 0.7f; // 0.0~1.0
layoutParams.alpha = 0.6f; // 0.0全黑 ~1.0原窗口
getWindow().setAttributes(layoutParams);
Toast.makeText(Main.this, "Set Dark", Toast.LENGTH_SHORT)
.show();
} else if (v == btnCancel) {
// 取消窗口变暗
layoutParams.dimAmount = 1.0f;
layoutParams.alpha = 1.0f;
getWindow().setAttributes(layoutParams);
Toast.makeText(Main.this, "Cancel Dark", Toast.LENGTH_SHORT)
.show();
}
}
}
@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 boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
以下是一堆布局：

</merge>还有形状文件，圆角矩形背景：
<?xml version="1.0" encoding="utf-8"?>
