Android 小技巧之 BaseActivity、BaseFr

1. BaseActivity.java

public abstract class BaseActivity extends AppCompatActivity {

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {

3. BaseDialog.java

public class BaseDialog extends Dialog {

    }

    public BaseDialog(@NonNull Context context, int themeResId) {

    }

    public void setProperty(int x,int y,int w,int h) {
        mWindow = getWindow();
        WindowManager.LayoutParams params = mWindow.getAttributes();
        params.x = x;  //设置对话框的位置，0为中间
        params.y = y;
        params.width = w;
        params.height = h;
        params.alpha = 1.0f; //设置对话框的透明度,1f不透明
        params.gravity = Gravity.CENTER; //设置显示在中间
        mWindow.setAttributes(params);
    }
}
