Android--等待loading

效果图：

package utils;

import android.app.Dialog;
import android.content.Context;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.Window;
import android.view.WindowManager;
import android.widget.LinearLayout;
import android.widget.TextView;

import com.example.water.R;


public class loadDialogUtils {

    public static Dialog createLoadingDialog(Context context, String msg) {
        LayoutInflater inflater = LayoutInflater.from(context);
        View v = inflater.inflate(R.layout.dialog_loading1, null);// 得到加载view
        LinearLayout layout = (LinearLayout) v
                .findViewById(R.id.dialog_loading_view);// 加载布局
        TextView tipTextView = (TextView) v.findViewById(R.id.tipTextView);// 提示文字
        tipTextView.setText(msg);// 设置加载信息

        Dialog loadingDialog = new Dialog(context, R.style.MyDialogStyle);// 创建自定义样式dialog
        loadingDialog.setCancelable(true); // 是否可以按“返回键”消失
        loadingDialog.setCanceledOnTouchOutside(false); // 点击加载框以外的区域
        loadingDialog.setContentView(layout, new LinearLayout.LayoutParams(
                LinearLayout.LayoutParams.MATCH_PARENT,
                LinearLayout.LayoutParams.MATCH_PARENT));// 设置布局
        /**
         *将显示Dialog的方法封装在这里面
         */
        Window window = loadingDialog.getWindow();
        WindowManager.LayoutParams lp = window.getAttributes();
        lp.width = WindowManager.LayoutParams.MATCH_PARENT;
        lp.height = WindowManager.LayoutParams.WRAP_CONTENT;
        window.setGravity(Gravity.CENTER);
        window.setAttributes(lp);
        window.setWindowAnimations(R.style.PopWindowAnimStyle);
        loadingDialog.show();

        return loadingDialog;
    }

    /**
     * 关闭dialog
     *
     * http://blog.csdn.net/qq_21376985
     *
     * @param mDialogUtils
     */
    public static void closeDialog(Dialog mDialogUtils) {
        if (mDialogUtils != null && mDialogUtils.isShowing()) {
            mDialogUtils.dismiss();
        }
    }

}

使用方法：

public class MainActivity extends AppCompatActivity {
    private Dialog mDialog;
    private Button btn_show_weibo_loading;
  
    private Handler mHandler = new Handler() {
        @Override
        public void handleMessage(Message msg) {
            super.handleMessage(msg);
            switch (msg.what) {
                case 1:
             
                    loadDialogUtils.closeDialog(mDialog);
                    break;
            }
        }
    };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        btn_show_loading = (Button) findViewById(R.id.btn_show_weibo_loading);
        btn_show_loading.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mDialog = loadDialogUtils.createLoadingDialog(MainActivity.this, "加载中...");
                mHandler.sendEmptyMessageDelayed(1, 3000);
            }
        });

        
    }
}
