android - 自定义吐司包括活动或android中的功能

Question

我想制作自定义吐司，点击按钮后会弹出搜索栏。

自定义吐司中的搜索栏出现，但搜索栏的进度无法移动。

这就是它的外观

对于代码，这是 seekbar 的活动。

 package com.example.froyo2;

import android.app.Activity;
import android.os.Bundle;
import android.widget.SeekBar;
import android.widget.SeekBar.OnSeekBarChangeListener;
import android.widget.TextView;
import android.widget.Toast;

public class BloodpressureActivity extends Activity implements OnSeekBarChangeListener{
    private SeekBar bar; // declare seekbar object variable
    // declare text label objects
    private TextView textProgress,textAction;
    /** Called when the activity is first created. */

public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.bloodpressure);


    bar = (SeekBar)findViewById(R.id.seekBar1);
    bar.setOnSeekBarChangeListener(this);

    textProgress = (TextView) findViewById(R.id.textViewProgress);
    textAction = (TextView) findViewById(R.id.textViewAction);
}

@Override
public void onProgressChanged(SeekBar seekBar, int progress,
        boolean fromUser) {

    // change progress text label with current seekbar value
    textProgress.setText("The value is: "+progress);        
    Toast.makeText(this, "Progress: " +progress, 2500).show();
    // change action text label to changing
    textAction.setText("changing");     
}

@Override
public void onStartTrackingTouch(SeekBar seekBar) {
    // TODO Auto-generated method stub
    textAction.setText("starting to track touch");
}

@Override
public void onStopTrackingTouch(SeekBar seekBar) {
    seekBar.setSecondaryProgress(seekBar.getProgress());
    textAction.setText("ended tracking touch"); 
}
}

这是按钮的侦听器，单击按钮后它将显示自定义吐司。

public void onClick(View v){        
    LayoutInflater inflater = getLayoutInflater();
    View layout = inflater.inflate(R.layout.bloodpressure, (ViewGroup) findViewById(R.id.seekBar1));
    Toast toast = new Toast(getApplicationContext());
    toast.setGravity(Gravity.BOTTOM, 0, 0);
    toast.setDuration(Toast.LENGTH_LONG);
    toast.setView(layout);
    toast.show();

}

Answer 1

Toast 无法接收触摸事件。删除代码的 Toast 部分，并将 View 直接添加到 Activity 的内容中。

LayoutInflater mLayoutInflater = (LayoutInflater)
    getSystemService(Context.LAYOUT_INFLATER_SERVICE);

ViewGroup mViewGroup = (ViewGroup) 
    findViewById(android.R.id.content);

View mView = mLayoutInflater.inflate(R.layout.yourlayout,
    mViewGroup, false);

mViewGroup.addView(mView);
