Android仿360懸浮小球自定義view實現(xiàn)示例
效果圖如下：
實現(xiàn)當前這種類似的效果 和360小球 懸浮桌面差不錯類似。這種效果是如何實現(xiàn)的呢。廢話不多說 ，直接上代碼。
1.新建工程，添加懸浮窗權限。
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
2.自定義一個FloatMessagerMainWindow
import android.content.Context;import android.graphics.PixelFormat;import android.graphics.Point;import android.view.Gravity;import android.view.LayoutInflater;import android.view.View;import android.view.WindowManager;import android.widget.ImageView;import android.widget.Toast;import com.android.view.FloatMessagePopleDialog;/** * Created by liupanpan on 2017/3/16. */public class FloatMessagerMainWindow { private Context context; private View view; private WindowManager.LayoutParams mParams = null; private WindowManager windowManager = null; private static FloatMessagerMainWindow floatMessagerMainWindow; public FloatMessagerMainWindow(Context context, View view) { this.context = context; this.view = view; showWindow(context); } public static FloatMessagerMainWindow getFloatMessagerMainWindow(Context context, View view) { if (floatMessagerMainWindow == null) { synchronized (FloatMessagerMainWindow.class) { if (floatMessagerMainWindow == null) { floatMessagerMainWindow = new FloatMessagerMainWindow(context, view); } } } return floatMessagerMainWindow; } private void showWindow(final Context context) {// if (!isWindowDismiss) {// Log.e(TAG, "view is already added here");// return;// }// isWindowDismiss = false; if (windowManager == null) { windowManager = (WindowManager) context.getApplicationContext().getSystemService(Context.WINDOW_SERVICE); } Point size = new Point(); windowManager.getDefaultDisplay().getSize(size); int screenWidth = size.x; int screenHeight = size.y; mParams = new WindowManager.LayoutParams(); mParams.packageName = context.getPackageName(); mParams.width = WindowManager.LayoutParams.WRAP_CONTENT; mParams.height = WindowManager.LayoutParams.WRAP_CONTENT; mParams.flags = WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_LAYOUT_INSET_DECOR | WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN; mParams.type = WindowManager.LayoutParams.TYPE_SYSTEM_ERROR;// mParams.softInputMode = WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE |// WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN; mParams.format = PixelFormat.RGBA_8888; mParams.gravity = Gravity.LEFT | Gravity.TOP; mParams.x = screenWidth - dp2px(context, 450); mParams.y = screenHeight - dp2px(context, 550); ImageView imageView = new ImageView(context); imageView.setImageResource(R.mipmap.icon_tab_item_message_pressed); imageView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Toast.makeText(context, "image=========", Toast.LENGTH_SHORT).show(); View view = LayoutInflater.from(context).inflate(R.layout.float_pople_room_layout, null); FloatMessagePopleDialog.getInstance(context, R.style.webviewTheme).setContextView(view); } });// floatView = new AVCallFloatView(context);// floatView.setParams(mParams);// floatView.setIsShowing(true); windowManager.addView(imageView, mParams); } private int dp2px(Context context, float dp) { final float scale = context.getResources().getDisplayMetrics().density; return (int) (dp * scale + 0.1f); }}調用方法：
FloatMessagerMainWindow.getFloatMessagerMainWindow(context, null);
實現(xiàn)到此 ，點擊按鈕就可以實現(xiàn) 懸浮窗。（此處可能會出現(xiàn)相應的崩潰，崩潰原因是懸浮窗的 懸浮權限開啟問題。）
4.我以官方模擬器為例開啟懸浮權限：
打開允許在其他應用上的管理權限
此時再次打開工程，點擊按鈕，就可以實現(xiàn)懸浮效果。
以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持武林網(wǎng)。
