如何在 Android 开发中将消息输出到 Eclipse 控制台

import android.util.Log;
public class MainActivity extends AppCompatActivity {
    private static final String TAG = "MainActivity";
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Log.d(TAG, "This is a debug message.");
        Log.e(TAG, "This is an error message.");
        Log.i(TAG, "This is an information message.");
        Log.v(TAG, "This is a verbose message.");
        Log.w(TAG, "This is a warning message.");
    }
}

D/MainActivity: This is a debug message.
E/MainActivity: This is an error message.
I/MainActivity: This is an information message.
V/MainActivity: This is a verbose message.
W/MainActivity: This is a warning message.
