应用

package com.fate.jumptomap;

import android.content.ActivityNotFoundException;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity implements View.OnClickListener{

    private EditText mAddressInput;
    private Button mAddressGo;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mAddressInput = (EditText) findViewById(R.id.address_input);
        mAddressGo = (Button) findViewById(R.id.address_go);
        mAddressGo.setOnClickListener(this);
    }

    public static Intent getViewPostalAddressIntent(String postalAddress) {
        return new Intent(Intent.ACTION_VIEW, getPostalAddressUri(postalAddress));
    }

    public static Uri getPostalAddressUri(String postalAddress) {
        return Uri.parse("geo:0,0?q=" + Uri.encode(postalAddress));
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()){
            case R.id.address_go:
                try{
                    Intent intent;
                    intent = getViewPostalAddressIntent(mAddressInput.getText().toString());
                    startActivity(intent);
                } catch (ActivityNotFoundException ex) {
                    Toast.makeText(this, "please install map app",
                            Toast.LENGTH_SHORT).show();
                }
                break;
        }
    }
}
