从 UI 过滤日志

Android 日志可以直接从 UI 过滤。使用此代码

public class MainActivity extends AppCompatActivity {
    private final static String TAG1 = MainActivity.class.getSimpleName();
    private final static String TAG2 = MainActivity.class.getCanonicalName();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Log.e(TAG1,"Log from onCreate method with TAG1");
        Log.i(TAG2,"Log from onCreate method with TAG2");
    }
}

如果我使用正则表达式 TAG1|TAG2 和我得到的水平 verbose

01-14 10:34:46.961 12880-12880/android.doc.so.thiebaudthomas.sodocandroid E/MainActivity: Log from onCreate method with TAG1
01-14 10:34:46.961 12880-12880/android.doc.so.thiebaudthomas.sodocandroid I/androdi.doc.so.thiebaudthomas.sodocandroid.MainActivity: Log from onCreate method with TAG2

可以将级别设置为获取给定级别及更高级别的日志。例如，verbose 级别将捕获 verbose, debug, info, warn, error and assert 日志。

使用相同的例子，如果我将水平设置为 error，我只会得到

01-14 10:34:46.961 12880-12880/androdi.doc.so.thiebaudthomas.sodocandroid E/MainActivity: Log from onCreate method with TAG1
