设置Dialogd窗位置

1、d窗Dialog
package com.lee.len.test.dialogdemo;

import android.app.Dialog;
import android.content.Context;
import android.os.Bundle;

/**
 * @description:屏幕保洁

 */
public class ScreenCleanDialog extends Dialog{

    public ScreenCleanDialog(Context context) {
        super(context);
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.dialog_screen_clean);
    }
}

2、d窗布局

3、调用Dialog的Activity

package com.lee.len.test.dialogdemo;

import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Gravity;
import android.view.View;
import android.view.ViewGroup;
import android.view.WindowManager;
import android.widget.Button;

public class MainActivity extends AppCompatActivity {

    private Button btnShowDialog;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        btnShowDialog = findViewById(R.id.btnShowDialog);
        btnShowDialog.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                showDialog();
            }
        });
    }

    private void showDialog() {
        ScreenCleanDialog dialog=new ScreenCleanDialog(MainActivity.this);

        //拿到LayoutParams，其实也就类似常用的FrameLayout.LayoutParams这种
        WindowManager.LayoutParams localLayoutParams = dialog.getWindow().getAttributes();

        //这里就是设置gravity位置了
        localLayoutParams.gravity = Gravity.TOP | Gravity.START;

        //xy就是d窗位置，这个位置可以自己随便写
        localLayoutParams.x =500;
        localLayoutParams.y = 100;

        dialog.getWindow().setAttributes(localLayoutParams);

        dialog.show();
    }
}

4、MainActivity的布局
