Dialog实现源码:
初始化:
private void dialogSELEctCallInit() { dialogSELEctCall = new Dialog(this,R.style.DialogPopBottom); View inflate = LayoutInflater.from(this).inflate(R.layout.dialog_SELEct_call,null); dialogSELEctCall.setContentView(inflatE); Window dialogWindow = dialogSELEctCall.getWindow(); dialogWindow.setGravity(Gravity.bOTTOM); WindowManager.LayoutParams lp = dialogWindow.getAttributes(); lp.x = 0; lp.y = 0; lp.width = getresources().getDisplaymetrics().widthPixels; dialogWindow.setAttributes(lp); RelativeLayout layoutVoice = (RelativeLayout) inflate.findViewById(R.id.layout_voicE); RelativeLayout layoutVideo = (RelativeLayout) inflate.findViewById(R.id.layout_video); Button buttonCancel = (Button) inflate.findViewById(R.id.cancel); RxView.clicks(layoutVoicE) .throttleFirst(2,TimeUnit.SECONDS) .compose(this.bindUntilEvent(ActivityEvent.DESTROY)) .subscribe(v -> { // dialogSELEctCall.cancel(); VoiceSessionActivity.startActivityCallOut(this,userId); }); RxView.clicks(layoutVideo) .throttleFirst(2,TimeUnit.SECONDS) .compose(this.bindUntilEvent(ActivityEvent.DESTROY)) .subscribe(v -> { // dialogSELEctCall.cancel(); // VideoSessionActivity.startActivityCallOut(this,userId); }); RxView.clicks(buttonCancel) .throttleFirst(2,TimeUnit.SECONDS) .compose(this.bindUntilEvent(ActivityEvent.DESTROY)) .subscribe(v -> dialogSELEctCall.cancel()); RxView.touches(layoutVoice,motionEvent -> { dealLayoutTouch(layoutVoice,motionEvent); return false; }).compose(this.bindUntilEvent(ActivityEvent.DESTROY)).subscribe(motionEvent -> {}); RxView.touches(layoutVideo,motionEvent -> { dealLayoutTouch(layoutVideo,motionEvent); return false; }).compose(this.bindUntilEvent(ActivityEvent.DESTROY)).subscribe(motionEvent -> {}); } private void dealLayoutTouch(View v,MotionEvent event) { switch (event.getAction()) { case MotionEvent.ACTION_DOWN: v.setBACkgroundColor(Color.rgb(200,200,200)); break; case MotionEvent.ACTION_UP: v.setBACkgroundColor(Color.WHITE); break; } }
显示对话框:
DialogFragment实现源码:
定义了一个类SELEctCallDialog.Java继承DialogFragment
package com.bazhangkeji.classroom.common; import android.app.Dialog; import android.app.FragmentManager; import android.graphics.Color; import android.os.bundle; import android.support.Annotation.NonNull; import android.view.Gravity; import android.view.LayoutInflater; import android.view.MotionEvent; import android.view.View; import android.view.ViewGroup; import android.view.Window; import android.view.WindowManager; import android.widget.button; import android.widget.RelativeLayout; import com.bazhangkeji.classroom.R; import com.bazhangkeji.classroom.session.VideoSessionActivity; import com.bazhangkeji.classroom.session.VoiceSessionActivity; import com.jakewharton.rxbinding2.view.RxView; import com.trello.rxlifecycle2.android.FragmentEvent; import com.trello.rxlifecycle2.components.RxDialogFragment; import java.util.concurrent.TimeUnit; public class SELEctCallDialog extends RxDialogFragment { private Dialog dialog; private String userId; /** * 初始化.必须调用一次 * @param userId: 目标用户id */ public void init(String userId) { thiS.UserId = userId; } @NonNull @Override public Dialog onCreateDialog(Bundle savedInstanceStatE) { dialog = new Dialog(getActivity(),R.style.DialogPopBottom); View inflate = LayoutInflater.from(getActivity()).inflate(R.layout.dialog_SELEct_call,null); dialog.setContentView(inflatE); dialog.setCanceledOnTouchOutside(true); Window window = dialog.getWindow(); WindowManager.LayoutParams lp = window.getAttributes(); lp.gravity = Gravity.bOTTOM; lp.width = WindowManager.LayoutParams.MATCH_PARENT; window.setAttributes(lp); RelativeLayout layoutVoice = (RelativeLayout) inflate.findViewById(R.id.layout_voicE); RelativeLayout layoutVideo = (RelativeLayout) inflate.findViewById(R.id.layout_video); Button buttonCancel = (Button) dialog.findViewById(R.id.cancel); RxView.clicks(layoutVoicE) .throttleFirst(2,TimeUnit.SECONDS) .compose(this.bindUntilEvent(FragmentEvent.DESTROY)) .subscribe(v -> { dialog.cancel(); VoiceSessionActivity.startActivityCallOut(getActivity(),TimeUnit.SECONDS) .compose(this.bindUntilEvent(FragmentEvent.DESTROY)) .subscribe(v -> { dialog.cancel(); VideoSessionActivity.startActivityCallOut(getActivity(),TimeUnit.SECONDS) .compose(this.bindUntilEvent(FragmentEvent.DESTROY)) .subscribe(v -> dialog.cancel()); RxView.touches(layoutVoice,motionEvent); return false; }).compose(this.bindUntilEvent(FragmentEvent.DESTROY)).subscribe(motionEvent -> {}); RxView.touches(layoutVideo,motionEvent); return false; }).compose(this.bindUntilEvent(FragmentEvent.DESTROY)).subscribe(motionEvent -> {}); return dialog; } private void dealLayoutTouch(View v,200)); break; case MotionEvent.ACTION_UP: v.setBACkgroundColor(Color.WHITE); break; } } }
