从活动传递参数给的BroadcastReceiver [英] Passing Parameters from An Activity to BroadcastReceiver

问题描述

嘿，我一直在试图传递字符串数组从我的活动广播接收器，但它总是给我在广播空接收我已经尝试过以2-3的方式。

  // code在接收器
串stringText = intent.getExtras（）的getString（string_text）;

// code的活动
   意图I =新的意向书（android.intent.action.PHONE_STATE）;
i.putExtra（string_text，ABC）;
 sendBroadcast（ⅰ）;
 

但接收端stringText总是空。我已经尝试过以另一种方式，但没有运气

 字符串文本=（字符串）intent.getSerializableExtra（string_text）;
 

但到目前为止没有运气谁能帮助我解决这个问题？

解决方案

 公共类GlobalVariable扩展应用{

  私有String []变种;

  公众的String [] getVar（）{
    回归VAR;
  }
  公共无效SETVAR（字符串[] VAR）{
    this.var = VAR;
  }
}
 

和我的活动称之为

  GlobalVariable appState =（（GlobalVariable）this.activity.getApplication（））;
appState.getVar（）
 

以上的code线检索类似的方式来设置

i.putExtra("string_text", "abc");

But till now no luck can anyone help me with this issue?

解决方案

public class GlobalVariable extends Application {

  private String[] var;

  public String[] getVar(){
    return var;
  }
  public void setVar(String[] var){
    this.var= var;
  }
}

GlobalVariable appState = ((GlobalVariable) this.activity.getApplication());
appState.getVar()
