printStackTrace、toString、getMessage的区别主要在打印的详细程度依次递减:
printStackTrace打印错误输出内容样式:
Name of the Exception: Message of the Exception
Stack trace
toString打印错误输出内容样式:
Name of the Exception: Message of the Exception
getMessage打印错误输出内容样式:
Message of the Exception
可以通过下面的例子对其进行验证:
package com.toby.personal.testlistview;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
public class MainActivity extends Activity {
private final static String TAG = "TAG_Test";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
try {
int test = 10 / 0;
Log.d(TAG, String.valueOf(test));
} catch (Exception e) {
Log.d(TAG, "================================Exception Start========================");
e.printStackTrace();
Log.d(TAG, e.getMessage());
Log.d(TAG, e.toString());
Log.d(TAG, "================================Exception End==========================");
}
}
}
运行之后控制台的log输出截图:
