android中textview记录日志,Android在TextView中显示Logcat

这是一个

blogpost,完全符合您的需要.它有一个完整的代码示例,介绍如何显示Logcat日志的内容.这是代码：

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStreamReader;

import android.app.Activity;

import android.os.Bundle;

import android.widget.TextView;

class ReadLogDemo extends Activity {

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

try {

Process process = Runtime.getRuntime().exec("logcat -d");

BufferedReader bufferedReader = new BufferedReader(

new InputStreamReader(process.getInputStream()));

StringBuilder log=new StringBuilder();

String line = "";

while ((line = bufferedReader.readLine()) != null) {

log.append(line);

}

TextView tv = (TextView)findViewById(R.id.textView1);

tv.setText(log.toString());

} catch (IOException e) {

// Handle Exception

}

}

}
